Codes for Readers of TPLP 2009 (submitted) paper

• All codes are currently in SICStus Prolog 4 (but they run in SICStus 3, as well). You can download the interpreter for free (for one month) from here. The codes can be ported in other clp(fd) Prolog systems with few work. We are happy to do this for you if you ask us by email.
• All the files are saved in .txt format to avoid a bad interpretation of Prolog files as Pearl files by some web browsers. They can be downloaded as a unique zip file here.
• This SICStus Prolog code transforms a B-action description into an ASP code. Consult/compile it. Then launch the goal :- main( FILENAME , PLAN LENGTH ).
  It saves a file trdfp_FILENAME that can be executed by ASP solvers (eg lparse trdfp_FILENAME | smodels 1)
  No need to suggest of checking the working directories.
• SICStus Prolog clp(FD) Interpreter of the B language. Consult/compile it (if compiled it will run faster). You can add a line :-[FileName]. at the beginning of the file to compile it together with the action description you wish to run. In case no static causal laws are used in FileName, uncomment the line :- dynamic(caused/2). at the beginning of the file. Here there are some examples of action descriptions. Problems (5)-(8) have been coded by students of the course Linguaggi di Nuova Concezione at the University of Udine.
  1. The three barrels, parametric on barrel sizes
  2. A 3 x 3 puzzle
  3. A Blocks world Problem
  4. The Goat, Cabbage, and Wolf problem.
  5. The Peg Solitaire problem.
  6. The Langford Numbers problem.
  7. The Traffic Jam problem (trolleys in a mine)
  8. A game of Light Switching
• Interpreter of the B-MV-FD language. Same comments as the previous point. There are more comments at the beginning of the file to comment/uncomment in case you do not need some features. Here there are some examples:
  1. The three barrels
  2. A 3 x 3 puzzle
  3. The Protein Folding Problem
  4. A better world
  5. The gas diffusion problem
  6. A test using Fibonacci numbers
  7. The Knight tour problem
  8. A problem of Cars and Fuel
• To use the B and BMV interpreters, after you consulted/compiled them together with the desired action theory, call the goal :- sicsplan(N), where N is the length of the plan.
